SPECIFICATION forming part'. of Letters Patent No. 376,014, datedJanuary 3, 1888.,

l Application tiled October 15, 1886. Serial No. 216,322. (No model.)

To all whom t may concern,.-

' Be it known that I, ALFRED C. REX, acitizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in the Manufacture of Loek Spindles, of which the followingis a specification.

My invention consistsv of an improvement in the manufacture of spindlesfor locks, my invention being more especially designed for themanufacture of spindles for the cheap combination-locks to be used inconnection with toy safes and similar articles, although my inventionmay be applied to the manufacture of other spindles. f

In the accompanying drawings, Figure 1 is a vertical section of atoy-safe door and part of the frame, showing the manner in whichlock-spindles constructed in accordance with my invention may beapplied.v Fig. 2 isa detailed view, partly in section, of the workingparts of thelock with the cover-plate removed. Fig. 3 is a perspectiveview of one of the notched wheels of .the lock, its spindle, andoperat-ingdisk. Fig.4isa side view showing the manner of turning thegroove in the end of the spindle. Fig. 5 is a side view of the spindleafter the groove has'been turned in it, but before the end has been cutby the die; and Fig. 6 is a view illustrating the manner of cutting thepolygonal end of the die. n

Referring to Fig. l, AA represent the 'walls of the safe, D the door,andEthe combinationlock, which is provided with a sliding locking-bolt,d, adapted to engage'with the jamb of the doorway or a keeper thereon.In the present instance I have shown the lock as provided with threenotched wheels, awhich are adapted to act on the inner end of the bolt dagainst the pressure of a spring, d. The

outer Wheel is mounted on a spindle, F,which is passed through the doorand provided on the outside with a suitable operating knob or disk, F.The spindles of the inner wheels are made tubular, so as to fit overeach other and over the central spindlebelonging tothe outer wheel, asshownin Fig. 1. The portion of the spindle F on which the wheel istitted is made many-sided, as illustrated in Figs. 2 and 3, and thecentral open/ing of each wheel is made of a shape to correspond, so thatthe combination u of the lock can be readily changed atany time bysimply removing the inside cover-plate of the lock, taking the wheelsoff their spindles and resetting them in other positions.

In order to construct these spindles with the least possible expense andyet with accuracy, I proceed in the following manner: After the spindlehas been turned to the proper diame ter I out in each a circumferentialgroove, j', by means of anysuitable cutter, s, asindicated in Fig. 4.The spindle thus formed, Fig. 5, is then put under a die, R, Fig.6,which cuts at o'ne operation the several sides on its end, theseseveral sides corresponding with the many-sided opening cut by thepunches and dies, as usual, in the corresponding wheel e. Owing to thepresence of thegroovef immcdiately behind that portion ot' the spindleon which the straight sides are cut by the die, a good clearanceis'aftorded for the metal in cutting, so that the sides are cnt cleanand straight.

I claim as my invention- The mode herein described of makinglockspindles with many-sided ends, said mode consisting in firstcuttinga circumferential groove near the end of the spindle, and thencutting the straight sides on the end of the spindle beyond the saidgroove by means of a die, all substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
